TL;DR: Oral administration with WEDZ for 28 consecutive days significantly decrease the intensity of hepatic damage induced by CCl4 in rats, and Liver histopathology showed that WEDz or PCA reduced the incidence of liver lesions.

TL;DR: The results showed that significant hepatoprotective effect was obtained against CCl4-induced liver damage, by oral administration of Helminthostachys zeylanica methanolic extract as evident from decreased levels of serum enzymes and an almost normal architecture of the liver, in the treated groups, compared to the controls.

TL;DR: Phospholipid complex of naringenin produced better antioxidant activity than the free compound with a prolonged duration of action, which may be helpful in reducing the fast elimination of the molecule from body.
Abstract: Naringenin is a naturally occurring flavanone, possessing a variety of biological activity. Due to its rapid elimination, naringenin needs frequent administration to maintain an effective plasma concentration. We have evaluated the therapeutic potential of naringenin-phospholipid complex under oxidative stress conditions compared with free naringenin. Naringenin-phospholipid complex was prepared and assessed for antioxidant activity in carbon tetrachloride intoxicated rats at a dose level of 100 mg kg-1 (p.o.). Liver function tests were studied by assessing serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum alkaline phosphatase and total bilirubin. Marker enzymes of liver, namely glutathione peroxidase, superoxide dismutase, catalase and thiobarbituric acid reactive substances, were measured to evaluate the antioxidant potential at the same dose level. The plasma concentration of naringenin was also measured. It was observed that the naringenin-phospholipid complex enhanced the antioxidant activity of the biomolecule and protected the liver significantly for a longer time as compared with free naringenin at the same dose level. Phospholipid complex of naringenin produced better antioxidant activity than the free compound with a prolonged duration of action, which may be helpful in reducing the fast elimination of the molecule from body.

  • ...Liver function tests and the antioxidant activity studies (Tables 1 and 2) showed that pretreatment with pure naringenin (100 mg kg−1) on alternate days neither reduced the elevated levels of SGOT, SGPT, SALP, total bilirubin and TBARS, nor increased the depleted levels of GPX, SOD and catalase....

TL;DR: The hepatoprotective and antioxidant activity of 50% ethanolic extract of whole plant of Amaranthus spinosus was evaluated against carbon tetrachloride induced hepatic damage in rats and suggests that possible mechanism of this activity may be due to the presence of flavonoids and phenolics compound in the ASE.
